Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538020, here are decompositions:

7 + 33538013 = 33538020
11 + 33538009 = 33538020
17 + 33538003 = 33538020
59 + 33537961 = 33538020
79 + 33537941 = 33538020
101 + 33537919 = 33538020
157 + 33537863 = 33538020
163 + 33537857 = 33538020

Showing the first eight; more decompositions exist.
